Action Of a Pair Of Mating Involute Teeth Let a and b be the base circles of a pair of mating involute gears. Line CD is a common tangent to the base circles. while b is the line of centers assume that CD is part of a string being unwound from A and wound upon B, while A and B rotate together in such a manner that string CD remains taut at all times. When A and B start to rotate, point C on the string will leave

The manufacturing(or production) process of a factory, in a broad sense, is the sum total of separate processes involved in the conversion of sum total raw materials or semi-finished products into final as far as products.

This 90 minutes lecture to be delivered via telelink addresses a class of mit undergraduates unrolled in Engineering Design and Rapid prototyping Course. The students have been introduced to the basic optimization concepts of design variables design space, objective function, constraints and numerical search methods. Building on this elementary basis, the purpose of the lecture is to make the students aware of a reaud range of theoretical and practical issues that arise when optimization is applied in real-life engineering. To that end a gamut of topics is presented with emphasis on the qualitative exposition rather than in-depth mathematics. The topics include

5 Heteronuclear Correlation Spectroscopy H.C-COSY We will generally discuss heteronuclear correlation spectroscopy for x =C(in natura abundance!), since this is by far the most widely used application. However, all this can also be applied to other heteronuclear spins, like 3P, 5N, 1%F,etc In the heteronuclear case, there are some important differences that allow to
